Answer:
1/9x - y = -5
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form: y = 1/9x + 5
<u>Step 2: Find Standard Form</u>
- Subtract 1/9x on both sides: -1/9x + y = 5
- Multiply -1 on both sides: 1/9x - y = -5
80 is correct.
-440+360 = 80
CF=EC=DC
2CF=CD
CD = 20 in.
Answer:
Let C be the position of a person in a helicopter. A,B be two objects lying opposite to each other on either bank of a river.
Let AD=x,BD=y
In ΔACD,

⇒x=130(1.732)=1212.4
∴ the width of the river =x+y
=1212.4+130
=1342.4m
